通过3D打印使用钙钛矿纳米填料增强PVDF基TENGs性能Enhancing PVDF-Based TENGs with Perovskite Nanofillers via 3D Printing
➀ 研究通过3D打印将多晶型FAPbI₃钙钛矿纳米填料掺入PVDF薄膜，显著提升了摩擦纳米发电机（TENG）的性能；
➁ 退火处理促使FAPbI₃从δ相转变为α相，PVDF的β相含量提升至83%，并形成介孔结构以增强电荷储存能力；
➂ 最终TENG器件实现392 V的峰峰值电压及2587 μW/cm²的功率密度，为微型电子设备提供了可规模化生产的可持续能源解决方案。
➀ A study demonstrates that incorporating polymorphic FAPbI₃ perovskite nanofillers into PVDF films via 3D printing enhances triboelectric nanogenerator (TENG) performance;
➁ Annealing triggers a phase transition from δ to α-phase FAPbI₃, increasing PVDF’s β-phase content (up to 83%) and creating mesoporous structures for higher charge density;
➂ Resulting TENGs achieve 392 V peak-to-peak voltage and 2587 μW/cm² power density, offering scalable, sustainable energy solutions for microelectronics.
